The Love number \(k_2\)  measures how easily the bulk
of the matter in a star is deformed.
The Love number also encodes information about the star’s degree of central
condensation.
Stars that are more centrally condensed will have a smaller response to a tidal
field, resulting in a smaller Love number.
The Love number decreases with increasing compactness, and from
Eq. (REF ) it can be seen that \(k_2\)  vanishes at the compactness
of a black hole (\(M/R = 0.5\) ) regardless of the EOS dependent quantity \(y\) .
The tidal Love numbers of strange quark matter stars
are qualitatively different from those of hadronic matter
stars [1]}, [2]}, [3]}. The latter decrease strongly for
small values of the compactness.
